For years I've had some changed images and sounds for this set. I've updated them to match the new set. I figure people might like them, so I've uploaded them.
The screens have a bit of the "legend" icons showing the relative order of government and economy types, as well as a function key menu with English labels (the old menu from the previous BGS set but with text added by myself -- now blended over the new backgrounds nicely). Here's a 16:10 screenshot: http://www.keeper1st.com/Oolite/bgsexample.png
For the sounds, I replaced the "Item Sold" and "Item Bort" (?!) with nice little chimes (can't remember where they came from -- original Oolite?), changed things like "Ortopilot activated" into "Autopilot activated", trimmed some dead air (e.g. so instead of "missile......armed" it's "missile armed"), removed all instances of Majel Barrett from Star Trek (nothing against the late Ms Barrett or Star Trek; I just think the second voice is unnecessary), and greatly changed the extremely long and drawn-out game-over sound into a rather rapid explosion then sudden expulsion of air into silence, which is rather more shocking and realistic.
You're free to add them to the pack if you like.
